Your problem seems very similar to one that occassionally (once a week) strikes us on one or other of two RSView32 that have very similar screens and Data base,
When we try to enter data into a data entry field it appears to accept the data, but that data fails to get the dotted outline on the data entry field that shows it has sent and read the data back, if we go off that screen and come back to it you see it has failed to be accepted. (Was not sent I think)
The work around that I have developed that works for us is,
Shut down RSView32 right back to the Windows Desktop,
Unplug all Ethernet or other Comms to the RSView32 PC and then restart RSView32 right up to the first screen which will have empty data fields wait, wait for long enough for it to scan all tags say 30 seconds, then plug the Ethernet or other Comms cable or cables back in.
My feeling is that RSView32 is trying to share an activation or is trying to share tag data with another RSView32 package that by shuting it down and restarting like this makes it run as a stand alone package that it is meant to be
Something I have posted before.
Just a different slant that may be worth trying.
Sometimes when edits are done in RSView 32, the project just does not want to release the cache files, and tries to keep running on previous settings.
A repair I do if any issue crops up, is to shut down the project, then in windows explorer, go into the project folder, open the cache folder, and blow away all files in that cache folder, they will be rebuilt on the next start up.
The next thing I do is go to the projects Tag folder, and look for one file with "the project name".cac
I THEN BLOW THAT ONE ONLY AWAY, leaving all the other files in that folder, this .cac file also will be rebuilt on project start up.
Then shut down computer and reboot and run your project.
I cant promise this will fix your problem, but it wont harm it either.
