Thanks for the info. More importantly, did you try the new version?

REGARDING your questions here:

I am running Windows 7 Starter, which I believe is 32-bit, but I may be 
mistaken.
No anti-virus running.
Don't really know what python is, so probably don't have another version of it 
running, hopefully!
Also not sure how to find default.db, doesn't come up on a file search of My 
Computer.
No funny characters in my username ("Chris")
Everything is on C drive.
Have had the problem without using the card browser, repeatedly.
I'll try the defragment this afternoon, and read up on the process monitor to 
see if I could figure it out without too much risk!  :)

   Good luck, Chris S.

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: 

http://users.ugent.be/~pbienst/pub/mnemosyne-20120709-setup.exe 

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!
