Bug: someone else has updated same information you have attempted to modify...

I keep getting this error and it makes the software unusable. I am the only user on the system, so it doesn't make sense either. I know it is just version 1 release but has anyone found a fix for this bug yet?

We tried restarting our sql server but it did not permanently solve the above problem.

Another bug I'm now getting: When click on Edit a Story I now get: "Teampulse has encountered an issue" with following exception.

That's great news! We will be eagerly waiting to try the next release.

Regarding the second bug, it came up probably twice in 30 minutes of use, so no, not that often. The first bug is what made the software unusable, so if it's fixed I'm marking this as answered.

Thanks!
