Hasta La Motion!

I just had for the second time today an alert from windows telling me there is not enough space on C:

I found that Nuke wrote 16Gb in
C:\Documents and Settings\…\Local Settings\Temp\nuke\processbridge

My cache disk folder is on the other partition of my HDD.

In my task manager, there are a lot of prcesses named: NukeQuickTimeHelper-32.exe

When I closed all of them (around 20 …) I was able to delete the content of processbridge folder.

I have been working with .mov files directly in my node graph maybe this could be one of the explanations to that problem.

I work on Nuke 6.2 v2.
Does anybody already had this problem? I don’t find anything on the internet.

Thanks in advance
