Version: (using KDE 4.1.0) OS: Linux Installed from: SuSE RPMs I just tried dragging and dropping a tab between konsole windows -- kudos for the great feature, that works nicely. What I've noticed is that when dragging tabs (even in the same window, to reorganize them), the output stays blank until either a keypress, a click on the widget or the terminal updates itself (because it's outputting). To reproduce: open a konsole, with two tabs, just doing nothing. Drag the 1st tab to be after the second, and there will be no text, it will be blank.
I've reproduced in current trunk too.
