A bizzare double click problem

I dont know if I am over sensitive, but double clicking in the left folder tree has a small probability not expanding the clicked folder which annoys me when I am expecting a flowy workflow.
Windows explorer doesnt has this behavior.

Happens for me too, seems to be random folders.

If it takes an abnormally long time to read the folder contents, the expansion may be cancelled. Could that be happening due to load or slow network drives or similar?

yep.

I am almost sure not the reason you mentioned. Just plain local random folders. Not a big issue to regular use, but hopesto be fixed. Similar other manager apps dont seem to have this problem, all precise and responsive.
