Ok guys... sorry for the stuff around.
The program is now fixed and should time OK.
I also fixed a little bug I noticed where the timers weren't displaying the time to go for the first second. The timing bug wasn't difficult to fix in the end... just a setting I missed
. Whew! I thought it was goign to have to be a complete rethink and rewrite, with a little bit of ugly maths, but it wasn't so serious.
I have placed the updated/fixed program on the first post in this thread. If you are one of the few people who down loaded the original, please uninstall it before you install the new version, just so you don't end up with a dud one still there to cause confusion (I don't think the install will replace the original).
Al.
