Welcome to TVPaint Community forums !

If I unassign the shortcuts the issue stops, which is great. One last question, is there any way to make this permanent in the preferences? Not that is a big issue, but everytime I start a new file, the preferences reset back to the original state. I guess, is there any way to permanently save prefe...

So I disabled all the buttons on the right hand side - and the problem still persists. Any other suggestions?

It has been updated to 10.5.3 and the same issues is still happening.

It does not happen with the mouse, but only with the pen.

Working with TV Paint and every time I make a stroke of the pen on the screen the brush size gets smaller and smaller. For example, if I start at 5.0. with each stroke of the pen, it drops to 4.5 and 4.0 and 3.5 and so on so forth, until it hits .10. Any idea on how to fix this? Mac OS 10.5 TV Paint...
