Weird issues with LV2009 when downgrading project version

[LVexpert2b · Accepted solution]

Hello folks,

After getting fed up of my VIs claiming that there are changes because of the "Disable Diagram.." (dirty dot problem).

I decided to breakdown one my VI's components. If copy & paste the block diagram onto a new VI, then the problem gets transferred as well.

After a few minutes of deleting different stuff, I found that my problem disappeared when I deleted the VISA resource constants.

I created a new set for my VI and bingo, the problem disappeared.  Just wanted to share my success and maybe some one can explain this weird issue.

Thanks

Thanks for posting your solution!  Not sure how that would cause the issue but hopefully this will help anybody else running into the problem.

I just wanted to add to my previous post that this applies to VISA/845x controls & constants.
