SBPRO 20 Windows 10 Tools get gummed up

For the last few days after working with SBPRO 20 the tools freeze up. For example I was drawing using the brush tool. When I switched to the stamp tool , even tough the icons reacted to the change, the brush tool remained active. another time when I switched to the brush tool the cutter tool was active even tough the brush tool was chosen. each time it was fine AFTER a re-boot. Something is getting fouled up in the program. Anyone know what can be done?

Out of curiosity are you on Windows 10 Version 21H2 and fully updated? Also are you using a Wacom? Might want to contact support and see what they say.
