Just a vent. 30 minutes plus wasted, my guess is an MS update, although I didn't think they updated on Fridays. Wacom tablet (old) was working just fine this morning. Doing a lot of work in Blender. 30 minutes ago (+) I went to use it and the pen totally stopped working in Blender after starting it from scratch. But the pen worked as usual on the desktop, so it was communicating with the OS. It was one of those WTH??? puzzles. I feel sorry for anyone who faces such a situation who is not a good troubleshooter. I feel sorry for myself, because of the headache! Clicked around and deleted and reinstalled the Blender options in the Wacom program. Didn't work. Finally found that Wacom had released an update for their drivers. So out of curiosity and prayer, downloaded it and installed. Everything started working again. Why would the OS stop sending signals to specific programs when a third party updates their driver? Did MS send some update that triggered the situation, 'cause unless Wacom has a time bomb in their code, nothing else makes sense. (Unless I have a virus, but my antivirus says no, and it stared working with the updated drivers.) Grrrr..... F whoever is responsible for such brain-dead decisions, or coding! PS - anyone know why my laptop monitor brightness would change when Blender becomes active? I've got a 24" monitor set up as the primary screen, and when I open and close Blender the laptop brightness changes (not the external screen). I've disabled Game Mode, and also killed the Dell display program, so I don't know what else it could be. Thought the two items were related, but they don't appear to be.

Blender is using DirectX which probably means that it's using Raw Input[^] and opening your HID devices with exclusive device access mode[^]. Exclusive access will fail if another program already has exclusive access. Most DirectX software (such as video games) do this.

Just a guess here... but Blender could be setting the ICC color profile[^] and doing calibration. It could also be a third-party library doing that, I think Blender uses an open source library OpenColorIO [^] for color management. Maybe you can ask about it on their Github issue forum. The events that occur on your workstation aren't always caused by an operating system update. :) Best Wishes, -David Delaune

I did not update Blender, the Wacom drivers, or do a manual Windows update, but Blender's response changed. The only realistic option I see is that a Windows update changed how it interacted with Blender. It may be related to the Raw Input you pointed out, but it only started working again after I updated Wacom's drivers. Unless Wacom has a time bomb check in their drivers that stop certain interactions under certain conditions.

You could very well be right. Thanks for the input, and have a great weekend!

PS - I even rebooted Windows and tried running Blender only, and the shenanigans happened.

I have lived with several Zen masters - all of them were cats. His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

Only 30 minutes? Come back when you've wasted days on some stupid issue :laugh: Any issue that didn't take you at least hours isn't even worth mentioning ;)

Been there, done that. That is probably why this only took 30 plus minutes. Once called OpenDialogBox (or whatever function it was) with one wrong argument. Felt really stupid that time. Another time had different compilation options for a DLL and the main project due to macros. That was a real head scratcher. But can diagnose that real quick, now! :laugh:
