i dunno if this helps you ricardo but a program i was debugging had this same problem in win 98 not in win 2k the program was using some trick to hook the int 3 and putting an iret at the start of interrupt handler and using
some sidt maneovere

so the first time it will run properly and olly will stop at the programs entry point but the next time olly will not stop at the entry point at all but will proceed to execute the exe and the cpu will be blank but the taskbar at bottom will say running

but sidt manipulating is possible only on 9x and not in nt

It's a problem with the sleep time in the plugin.
If it is too short, process is not see as debuggee process !
I have modified sleep time to 1s and it works well for me !

it doesn't work on a few of my programs - instead it creates access violation.

I think I have found problem by looking in sources. You get a pointer to the process block via FS segment in the CURRENT process and then write to that address which is in ANOTHER process. You need to get this address in the process being debugged, not the process which is the plugin, as they could be different.

Also, is it possible to also add ability to change Ollydbg window title? Some programs look for this window and bomb out if it's found.

Thanks!
