Clear description of the problem - try and include as much information as possible, including what button and mappings you are having problems with (if applicable).:

During my hdd housecleaning, I noticed XMouseButtonControl.log, a sizeable file and constantly growing with repeated messages and by trial and error I found out to stop this repeating message, I had to stop a Microsoft service "Tablet PC Input Service". Hope this can be fixed. Or is there a way to disable the log?

That's interesting - especially the solution. If XMBC injected messages are getting changed, there are almost certainly going to be other problems than just the log increasing (it logs that as an error for a reason!), so maybe the best solution is to remove the offending application anyway. But you can start XMBC with the argument /nolog if your are not noticing any problems and just want to cut out the logging. I suppose I could also modify XMBC to make that a debug only log. Right now, using the installed version, you'd need to modify the startup entry in the registry to add that CLI option so its a little complex in that regard!
The log file will never grow more than a certain size - it does have code in there to manage itself (I cant remember for sure but I suspect that size is around 10 or 20Mb - hardly an issue on a HDD but I guess I could see why you might not like it if you had a SSD and are particularly worried about write wear).

I believe this Microsoft service was turned on when I purchased a drawing tablet some months ago. Will need to connect back that tablet to see what's the impact of stopping this service.

You are right my concern is for the SSD lifespan.

Thanks for the /nolog option, will get it done in regedit.
