paint tool sai

i am trying to use window capture for paint tool sai however the "window" is based off of the name of the application, which changes depending on which canvas i am in, with obs recognizing each canvas as its own new window this is inconvenient for window capture where i would like to capture...

So I stream art and I use OBS. But now it won't open when paint tool sai is opened, so I tried opening it after but OBS crashed. Please help

So, I tried recording Paint Tool SAI. I tried window capture, game capture and nothing worked. I clicked Paint Tool SAI but whenever I go to chrome or any other program, it records that too. It worked before but it broke now. Is this broken or am I doing something wrong? P.S I used the 64bit...
