Strange scrollbar in Analysis:Matrices

problem

In Statistics : Analysis : Matrices, there sometimes appears a scroll bar at the bottom of the Matrices window. (this scroll doesn't appear if you open Statistics : Analysis : Matrices and previously you left Statistics : Analysis with the Matrices window on, so in order to see this scroll bar, first you have to close Statistics : Analysis with something else left on, e.g. Use, 3-D Graphs or Forgetting Curves, etc). When you click this bar, the following error appears: Access violation at address 5B1FA07F in module 'uxtheme.dll'. Read of address 00000004.

note

• it is easy to reproduce the appearance of the bar, however, the error in uxtheme.dll does not seem to show up (Vista or XP).
• it seems SuperMemo bothers to resize the matrix only if you open it in Analysis on startup, otherwise it remains in its original size with a scrollbar (which can be considered a bug)
