Just to possibly help in solving this bug.
I have been using gtsdll for about 2-3 years. Great work guy's, And awesome to see all this work being done again

Well, I use utorrent, and was pleased to see the uttorent support for gtsdll (I used to use azureus, so spammed away my downloads back when).
Now, it worked just fine when I initially turned on the dynamic pop-ups. And was a sweet feature. Then maybe 2 day's later, right click caused mIRC to freeze.
I then went into the config, and changed the name of the utorrent config. And started mirc. Lo and behold, right click worked a treat, renamed the utorrent conf back to it's original name. Right click cause mirc lock up again.
So, to me, all signs seem to point to Utorrent.
Is everyone else having the same problem usint utorrent?
