I get exactly the same behaviour when running Phex 0.5.0 in Linux...

Search for something...
...get results...
Search for something else...
...start getting results....
...then Phex completely freezes :-/ hmmmm

Doing a "top" shows that Phex at this stage isn't hogging the CPU or anything, it's just sitting there looking at me completely frozen - a minimise/maximise and the window is completely blank/grey, showing that the program's not updating the screen.

It's a pity Phex is doing this, coz I think it's a great program, if it didn't exhibit that annoying feature

Rgds.
