When I call a windows explorer from an app (open/save file), as soon as it closes (whenever clicking cancel or actually saving/opening a file), the app will freeze for 3-15 seconds. Nothing particular showing up in the performance montor*, I don't know where this is coming from.
*Said freezing application takes 0% of CPU/Disk but has status "not answering"
While this is not a verious serious problem, it becomes very very irritating when I'm coding and saving new files every few minutes.
It happens on a lot of different software (Sublime Text, thunderbird, firefox, etc.) and the common factor really is the "save as" commands that call a browser. It doesn't happen at all when I open a regular explorer with WIN+E.
It is quite strange, because the problem disappears for "consecutive saves" (ie If I do a "save as" just little time after a previous one on the same app, it won't freeze at all most of the time)
I've also tried to hunt&kill processes to see if it would change anything, but so far I haven't found the culprit.
I believe I didn't have this issue after a fresh Windows install. Because I'm doing a lot of development, I highly suspect this might be related by some software that watch folder updates, but I have no idea how to track the problem. Also the fact is that only the application that asked to save the file freezes kinda puzzle me. Any advice on this ?
I don't believe the Hardware is relevant, as it happens on both my desktop and laptop. They both run Windows 8. My desktop is quite a powerful machine, with SSDs and an intel i7.
EDIT : running processes
EDIT : running services (I guess I bit of paint.net doesn't hurt...)
