Seems to be a weird behavior of the canvas menu. If a patch window is located in the lower half of my desktop the menu tabs "put" and "edit" don't work properly, i.e. instead of: click > dropdown menu appears below

click > dropdown menu appears over the tab itself (thus causing unwanted objects to be accidentally created, for example...)

See attachments. It does not happen when the patch is located in the upper half of the desktop.

Anybody experienced the same?

I'm on Ubuntu Jaunty pd-ext rc5
