When I click the 'Interactive SQL' button on my IBConsole, no window appears. It is listed when I then click the 'active windows' button, but selecting it and clicking 'Switch to' does nothing. Is there a known cause for this, or logging somewhere on my system?
It turns out the problem was caused by a corrupted IBConsole.xml settings file, located in C:\Users\myname\AppData\Roaming\Embarcadero\InterBase
The cause is unknown to me, but I replaced the file with a colleague's copy, and after that my Interactive SQL window functioned as normal.
