transform not activating

Hi i use toon boom harmony advanced with a yiynova msp19u tablet. Every time I click the transform literally nothing happens the button itself shows that it’s been clicked but nothing is showing as being selected i get the “no” symbol (circle with line through it) when i try to select something…

what could be the issue here and how do i go about fixing it?

A screenshot of the entire software window might help
to show the context.

cant it only happens when i use the tablet it seems no idea why… but if i close the tablet to take a screenshot of the circle with a line through it which is now my cursor toonboom closes and has to be reloaded

Try going into the preferences of Harmony and on the “Advanced”
tab, uncheck “Use QT Wintab Tablet Support”. Then close and
relaunch Harmony.
