Hi,
inside BEDIT, you hit the visibility states button or start the BVSTATE command
In this moment you can do NOTHING, until you hit [ESC]
Right?
If so, so this and nothing else between the steps:
Hit ESC and again visibility states button or start the BVSTATE command
Now, press [ALT]+[SPACE]
<the cursor should disappear after the next step>
followed by [M] (for englisch OS versions)
and now hit one arrow key (not from the numpad)
Move the mouse in circles or from left to right, top to buttom until you see the cursor (with the dialog) again.
