Repeatable Hard Lockup

Using XP sp2 and FlashFXP 3.6 demo. If I choose a local file to transfer that also exists on the remote, I get a popup asking if I want to overwrite, rename, etc. One of the options is "configure"-- if I click on that button I get a menu asking me about file exists options. I click cancel on that menu and the entire program locks up hard, to the extent that I have to do a ctrl-alt-del to kill it. I can recreate the bug 100% of the time.

is that an original install or cracked version?
what build of flashfxp?

Original version, FlashFXP v 3.6 build 1240, downloaded Oct 18, 09 from this site. I did have the remnants of an old install from when I tried FlashFXP back in 2007 and then uninstalled-- the dat files were still in place-- sites, bookmarks, etc., but that's all-- no exe's, dlls

I have confirmed this issue in v3.6, the latest beta version does not appear to exhibit this issue.
