This problem experienced since the first beta in both Win and Linux versions.

When a function (like a line) was selected for use and one press ESC twive to get back tot he main menu, it sort of does not cancel that last function. If one wouls now press on another function (like edit or circle) QCAD goes back to the line function.

the only way to rectify this is to press Esc many times. Sometimes the process needs to be repeated more than once.

I could not yet devise a sure fire way of reproducing this, but it does seems to happen as soon as the drawing gets bigger. I could not make it work with a clean page.

Although not crippling, it does break the elegance of drawing seamlessly and is a bit frustrating..

That said, I find QCAD 3.0.0 now significanlty faster than the Betas when loading and zooming in and out.
