List of Bugs

Bugs in SweepMe!

Description	Implication	Status	Fixed in Version	Workaround	Comment
Hierarchy offset when modules are unchecked	When an unchecked module is above the following: Loop with Reduction mode: Data from the wrong dimensions will be reduced, or measurement stops due to error. Condition / ControlWidgets / WaferProber using Skip sweeps below feature: The sweeps will not be skipped or only at a lower hierarchy level. CustomFunction using tuple arguments for measurement data: Passed data might be truncated if data is not in the same branch as the CustomFunction.	Fixed	1.5.6.20	Reorder modules or do not uncheck modules that are above other modules making use of one of the features mentioned in the Implications.
Saving setting does not continue when one module has an exception	Setting file is in incomplete and setting cannot be restored	Fixed	1.5.5.48	So, far this bug has only been observed with using Form module where the an exception is raised after the save check boxes disappeard because of another bug. There is no real workaround. Try to continuosly save a history of your setting file to restore a setting in case you saved it with wrong information.	Please update to a newer version
Modal dialogs can be hidden behind other dialogs	Some dialog windows have exclusive input (i.e. no other UI interaction is possible), but they are hidden behind other dialog windows, leading to a state where a user cannot interact with SweepMe! any more.	Fixed	1.5.5.47	Try to avoid opening multiple setting and option dialogs in parallel. If you already are in the bug scenario, use your keyboard to close the hidden modal dialog (Esc or ↵ Enter).	-
Widgets are not correctly saved to settings	After loading settings, widgets are floating or at wrong position	Open	-	Save setting, reload, fix widget and resave setting.	in progress
Unchecked widgets are not saved to setting if setting is saved during run	Setting cannot be reloaded correctly.	Fixed	1.5.5.34	Do not save settings during run	Please update to a newer version
Removal of a floating widget during a run using the right-top corner cross in beta version <=1.5.5.33	Programm crashes	Fixed	1.5.5.34	Do not close the widget during run	Please update to a newer version
"Delete version" in version manager deletes entire folder "CustomDevices" for beta version 1.5.5.1 to 1.5.5.8	Loss of all custom Device Classes	Fixed	1.5.5.9	Do not use button "Delete version"	Please update to a newer version
Only a single 1D data file with Loop = nonstop	Missing data	Fixed	1.5.3.22	-	Please update to a newer version
Seldom, random freezes in version 1.5.3.x	Program does not react	Fixed	1.5.3.21	-	Please update to a newer version
Plots with the same name are overwritten	Not all images are saved	Fixed	1.5.1.14	-	Could be problematic when plots show the same but with different slicing
Using 'stop' functionality does not work	Measurement aborts	Fixed	1.5.3.16	-	Please update to a newer version

Known Issues

Issue	Description	Recommendation	Comment
Windows Update forces a restart and interrupts measurement	Especially in Windows 10, Windows has a strict update policy and forces restarts of your computer, even if applications like SweepMe! are still running. This can interrupt a measurement and in the worst case damage your equipment.	In Windows 10, you can define Active Hours, during which Windows will not install updates and restart. For long-running or over-night measurements, set the Active Hours accordingly. As an administrator, you can set a group policy that Windows will not resart as long as a user is logged in.
After changing the name of a DeviceClass, the setting has to be renewed	The setting does not work anymore. 'Find ports' does not load any ports.	Please change the DeviceClass to the new one and save your setting.	We will introduce a DeviceClass ID to the setting in a future version to overcome this issue.
Nesting of modules limited to 30	A single branch cannot have more than 30 modules in the sequencer (This limit does not affect modules that are in different branches). SweepMe! relies on numpy arrays to store and process measurement data, and numpy has a limitation to 30 dimensions.	Consider to rearrange the modules depending on your measurement setup, or combine the functionality of multiple modules into a single CustomFunction, if possible.	In the next major SweepMe! version we can upgrade to the latest numpy that extends the limit by a factor of 2.
