Am I the only one or does this version have the tendency to go of the rails?

The last few weeks I have time and time again that some bit of routing suddenly for no apparent reason lights up yellow or even red.

The 'what's wrong' message only gives a very unhelpful message. The red dashed line showing where the error occurs shows the entire route. Troubleshooting the offending route gives no solution.

What does work however is : Close SW down. Restart it and everything is hunkydory again.

Until.... at some point it decides it isn't.

The fake error even pops up if I, while having the top ASM open, request to open a sub-ASM which has absolutely nothing shared with the routing ASM's, don't alter a thing, close it and some routes give errors. Ah, I hear you think, it's because of a rebuilt. Wrong. Because no matter on what level I do a force rebuilt, everything is fine.

Another thing that happens is that by using 'Cover' on a route I get the typical circular reference problem, as in it keeps telling me that it has to be rebuilt.

Remove the covering and all's well. Put a bit of covering anywhere on the route and it's back.

Yep, it sure helps that we only have to deal with what we want to design, imagine what time we would lose if we had to deal with the software being a PITA.
