TexturePacker crashes everytime it tries to open a "Save / Open File Window Dialog"

Hi !

I know this isn’t a Texture Packer but I’m gonna ask anyway : TexturePacker seems to work fine, until it tries to open a “Save as window” or “Open window”. It actually freezes, and I can’t do anything except killing the app.

I’m running on Windows 8.1, I’ve tried both x64 and x86 versions, as an admin too…

I’d really love to use it (I really need to use it in fact…) but I can’t. Does anyone has the same problem ?
