Hi,

As you know, there have been quite some reports of Mnemosyne sometimes hanging on Windows. I had hoped that the new PyQt version would fix this, but unfortunately, that turned out not be the case. The hangs never happen on my system, so I need help to debug this.

To summarise what I understand the problem to be (but feel free to correct me), Mnemosyne sometimes hangs when trying to grade a card, and this happens regardsless of whether the cards contain images or not. It happens both on XP 32 bit and on W7 64 bit.

I prepared a new test version here:

I changed some small packaging/configuration options. I'm not sure if they will have a big impact, but you never know :-)

If you still have hangs, it would be interesting to see if how the frequency of hangs changes if you try e.g. 'autosave after 1 reps' vs 'autosave after 20 reps'.

If you have a virus scanner like Microsoft security essentials running, please try disabling it and see if it makes a difference. Ditto for Windows desktop search.

If you have a separate version of Python installed on your machine, please remove it.

Do a search for default.db on your file system, and check if default.db has write permissions, together with all the folder levels above it.

Do you have funny characters in your windows account name?

Is your database on the C drive?

Do you also have the problem if you never used the card browser after starting the program?

If you're technically inclined, run Sysinternal process monitor while running Mnemosyne, to see if anything suspect happens with database access (filter to show only events in the 'file system' class) ( http://technet.microsoft.com/en-us/sysinternals/bb896645 )

Make sure you have enough free disk space and try running a defragmenter.

Any other pattern you observe or thought you might have to solve this, is welcome!

Peter
