Version 0.19 has been released. It can be found here:

Changes in version 0.19:
* Fixed locking issue with Popup Stats.
* Fixed (another) bug with Self stats.
* Fixed bug with $.50/$1 limit.
* Improved performance of icon drawing.
So with version 0.19, there should be no more lockup issues, at all. Also, your Self stats should be accurate at all times now. I believe I've found and fixed the source of the "flickering".
So there you go. If you have any problems with version 0.19, please let me know. Hopefully this will be the last release before PokerStars support.
