Centering occasionally freezes with 2.5.1.17

Since upgrading to 2.5.1.17, centering often freezes during Step 3 and Step 4. Never seen that happen before. Using G11 with ASCOM v 1.0.56.0. Log below when freeze during Step 3 and Step 4 and then I abort after a minute or so. Text at bottom of window says “Image preview opened” when frozen.

STEP 3 FREEZE…

I have the exact same issue with my CEM60 and Trius 814. Any suggestions?

Thanks Tim for confirming, This is definitely a bug that was introduced in one of the latest revisions. I’m hoping one of the developers acknowledges it. It’s been slowing me down considerably over the last few weeks. I need to repeat centering 3-4 times to get around this periodic “freeze” bug.

Sorry, we have acknowledged this one many times… this thread just slipped through. The fix is in the 2.5 beta.

Thanks Ken!
