FlashFXP hanging/not responding when connecting

The bug cannot be reproduced on demand since it occurs randomly (but fairly often).
I try to connect to two sites and FlashFXP gets stuck in "Not responding" mode and it doesn't recover anymore and I have to kill it.

Operating System : Windows 7 Ultimate
FlashFXP version: 4.2.1 (build 1745)

It started happening for the first time one or two builds ago.

I have a screendump available but I dont know how to include it with the ticket.

Hello,

I believe this issue should now be fixed in the latest beta release, you can download beta releases from within FlashFXP.

It's still happening with beta 1749 :-(

I've confirmed this happens often for me too. Particularly when I am connecting to two sites at one time in different panes.

Operating System : Windows 7 Ultimate
FlashFXP version: 4.2.1 (build 1745)

A new beta has been released to address this issue, how do I download beta updates?

Please let us know if you continue to encounter this issue after updating.
