If you ever encounter slow downs using the "Inventory Status" module, and especially switching between rows, please read the following workaround:

The main reason is about the user interface layout customization files.

After several software updates, those files can be corrupted and slow down the display process of the grids: there is no real way for us to prevent this behavior, because the users can arrange their grids in thousands ways.

The workaround is to open the following folder: C:\Users\[USERNAME]\AppData\Roaming\Blue Eye\Layout and delete all files.

where [USERNAME] is to be replaced by the windows user name used by the current session.
