I've been running the latest versions of Max/MSP/Jitter on my XP machine for a while now.
I'm working only with QT (no OpenGL stuff).
I have a problem that didn't exist before. Don't know when it started. I think a few days ago, but I didn't really catch it until now.
I run any of my Jitter patches.
When I grab a window's title bar to move it or close a window(main patch, subpatches, Max's preferences window, etc.) or open a menu from Max's menu bar, the video output pauses.
I pauses both in my pwindow and the output of jit.window.
The video motion returns when I release the window, move it around, or it finishes closing.
I've played around with all the performance options (including the "default" positions.)
I've played around with all preferences I can think of.
It happens with the following very simple patch.
Any advice appreciated.
