I love the polar alignment wizard, but recently have been having an issue with taking the three images. The very first time I start it, the image seems to be 1s exposure regardless of what I have set, so I stop and restart, then the exposure is the correct length.
The 1st exposure is then solved and the mount moves. The 2nd exposure is then started, but always fails with "Cannot capture while CCD exposure is in progress. Retrying in 10 seconds...". Some times it does continue in about 10s, but most of the time it is a lot longer, a couple of minutes or more. Then once this has actually got an image and solved, I get the same for the third image.
At this point all I have done is start kstars, connected to my equipment profile, gone to polar alignment, selected my guide scope and set the exposure to 3s. No other cameras are taking images to the best of my knowledge.

Apologises for lack of debug information, but I cant find the post that tells me what to supply. I swear I have seen one some where?!

Anyway, here is the log for polar alignment
