Upgrade to 1.5 --- Tool Matrix toolboxes dissapear

Windows 7 32-bit

All settings were restored from 1.4 except the toolboxes in the Tool Matrix.  These appeared checked but were not visable in the Tool Matrix panel.  When unchecked and re-checked again they are fine and are saved when DS is restarted...

... so this is minor

 

Windows 7 64-bit

All settings were restored from 1.4 except the toolboxes in the Tool Matrix.  These appeared checked but were not visable in the Tool Matrix panel.  When unchecked and re-checked again they show up again UNTIL DS is restarted... then they are lost again.

Problem tool matrix is practically unusable since it needs to be reset every time
