ESC key non-functional in text entry dialog in Logic

[sophiapoirier]

In the great tradition of the text entry dialog (contextual menu items "type in a value" and "type in a MIDI CC assignment") breaking in Logic every time VSTGUI changes (see #19 and #29), updating to VSTGUI 4.10 (812e42e) has broken ESC key functionality. The first press of the ESC key is ignored, and subsequent presses will flash the screen ("visual bell").

This seems to be a new side-effect of the workaround added to address #19 #29. Removing the workaround resolves this issue, however that first and more serious issue still requires a workaround.
