I tried to calculate the ICM of a decision while playing a $5.50 SNG in game. It completely bricked my 888 and PokerTracker client until restarting them. Behaviour I have observed on several occasions:

1. Inability to click call, fold etc until restarting the 888 client by ending relevant processes using task manager. I can't even click the close or minimise button in the window.
2. Same but for PT.
3. The calculation is attempted but no results are displayed in the hand reviewer.

Just wanted to see if anyone else has experience with this, or whether its just my computer (everything works fine unless using the ICM calculator).

I've learned my lesson to obviously not do ICM calculations in game, but if its not my computer this is a very aggressive, unacceptable anti-ICM "feature" which should have been implemented as on pokerstars.
