On the Hotfix_SPB17.20.005_README_CCR.txt file, you can read the following text: "1588769 ALLEGRO_EDITOR UI_GENERAL ALT+key shortcuts are not available in 17.2".
BUT this problem are NOT FIXED ! NOT fixed also on the next HotFix releases 006 and 007 !
Need to press at least 2 time the ALT key and WAIT some time, for enabling "FILE" anf others menu, but the sub menus features not responding as required ! There is a very big problem to use shortcuts, and for activate menus ! In the 16.6 release ALT+key there is NOT a problem.
A workaround or solution are very welcome. If you have please share it !
Thanks, Gianni.
