Details

This patch fixes the problem with fwpatcher that meant it'd attempt to patch all the time. The problem was that the commandline driven interface used WM_USER as signal to start patching. This signal is reserved and will be generated for a lot of different commands. The solution is to use something in the range 0xC000-0xFFFF which is available for applications as signal instead as per http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrfwmuser.asp

Patch severity set to High because without it, keyboard navigation is completely impossible Priority immediate because I don't think 3.0 should be allowed to ship with an fwpatcher that is not accessible (that is of course if fwpatcher is to be used for 3.0).
This task depends upon

Reason for closing:  Accepted
Additional comments about closing:  Alright, all\'s fine then. I was just a little curious why the fwpatcher had not been updated to include the fix and thought you might have forgot.

Ooops, read that wrong. The correct range is 0x8000 - 0xBFFF. Fixed patch attached.

Just making some noise, since the distributed fwpatcher in the wiki has not been updated to include this fix.

IMHO, this must be done for 3.0.

Yes, the bootloader must be updated anyway so these fixes will be included, as they are in CVS already.
