Solved Thumbnail viewer F7 or F8 actions don't work.

[ineuw]

I am using Irfanview 4.38 from where I activate the Thumbnail viewer. When selecting images and tapping F7 or F8 keys, nothing happens. There is no folder dialog which should display. I reinstalled the package over the old installation but nothing changed. Using Windows 7 Pro 32bit. Please help.
