This is a weird one. On my laptop VMS has the timeline zoom bar blacked out. You can still use it (tool tips appear and you can guess where the buttons are) but obviously this is a real pain. It was originally ok but happened while I was trying to fix rendering crashes (now sorted).
I have tried reinstalling several times including deleting registry entries and re-booting bewteen uninstall and re-install and it still comes back the same?
The same installation disc installs and works fine on my desktop.
