I've seen that message. This one is different. The message I'm talking about is actually an explanation of what went wrong with the last operation I tried to perform. I was performing a roof operation, making a barrel roof.
When I got to the end of the operation, the error message flashed on, it's about four lines long. The first sentence read something like " the roof cannot be formed. The arcs and lines you have selected........" I later realized I had one arc segment under another arc segment which is not allowed.
When I corrected this the roof was constructed and the error message did not come on.
There must be some way to make that error message stay on the screen for a longer period of time.
