Anyone reported this?

Select the whole text by painting it with mouse starting from bottom of the file and finishing to top (this order and using mouse to do this is important), then press the Delete-key. In my setup it kills Plato everytime.

My setup is:
Windows 7 x64, Current FTN95 Personal Edition with Plato v. 4.51.

Yes, I can confirm this behaviour in Win 7 64 - tested on a Lenovo notebook, but using Plato 4.4.0 according to its About box. I agree that it occurs when the mouse is used to select the text from the bottom to the top. The message is "Plato has stopped working". The error does not occur if you highlight the bottom of the file with the mouse, scroll up to the top, then select the top of the file and its contents with a Shift-Click operation, only if you select from the bottom to the top as Jalih notes. It doesn't exhibit the problem if only part of the file is selected. I haven't tried any other tests.

I have not been able to reproduce this effect on my Windows 7 64 bit machine. For the moment I note this a an unresolved issue.

Curioser and curioser. Plato3 (i.e. 3.3) does it, but 4.4.0 does not, on a 32-bit Windows 7 machine.
