Re: Win+E integration

Then maybe you should short-press it 
I am sorry for this...shpkong wrote:hyzhangzhy!
Your program launch dozens of XYplorer instance when long pressing Win+E...
which stuck my OS...
I try a mutithread implementation which I think may be better...
Now all the launch and switch to XYplorer stuff are done by another sep thread.
The keyboard hook thread will only set some event for that sep thread which should not block it and cause some problems...
Try it!
