"Preview" in file picker dialog renders app unusable

[gimpster]

Repro steps:
1. Launch Beyond Compare
2. Under "Start a new Session" click "Text Compare"
3. In the left file pane, click the folder icon next to the file path bar
4. Select a file but do not click "Open"
5. Press the spacebar to open the "Preview" of that file

Expected:
A preview dialog is displayed so that the user can preview the contents of that file, pressing the spacebar again would dismiss this preview and allow the user to open the file.

Actual:
A preview dialog is displayed, but the contents of the file are not displayed in the dialog and the dialog cannot be dismissed by pressing the spacebar again. In fact, clicking the "X" in the top-left corner of the dialog window will not dismiss it, and neither will pressing "Esc". The file picker dialog cannot be dismissed and the entire Beyond Compare application cannot be quit, except by performing a "Force Quit" operation.

Hello,

Thanks for the report. We've run into some trouble with the file browse dialog. I've reproduced similar hangs and will document this case, too.
