Assertion failed on copying files

Hi

Steps to reproduce:
1. Copy file from remote to local
2. Cancel the copy process
3. Try to copy it again
4. Get a nice box with "Assertion failed: Terminal && Terminal->active, file: d:\martin\Projekty\WinSCP2\forms\CustomScpExplorer.cpp, line134"

Is it maybe possible to make the error-message copyable so you can copy it and not to write it?

Thx,
Christian
