sure will and thanks ill just send the vi its in tommorrow morning many thanks

hi im using labview 6.1. i have a frame in a sub-vi that that reads 16 bytes from com7 (in my pc) into a global variable using a custom DLL. this variable is then used later to compare some data in another sub-vi. this was working fine for a day, then this morning i started it again and ran it. when i got to the point where this "read" happens i got a dr watson exception message. (i am running the application on nt4 in the development environment). after this point the gloabal had rubbish in it whenever i did a read, although it did also hold the basic read data. after a reboot etc it still did it. the fix was to completely remove this global from the application vi and my file globals.vi , create a new one and then use that in the same manner. everything was ok for an hour. then the same thing happened again. any ideas? this is really annoying.
