Hi -
I am getting different inkey and event codes if the right or left Alt
key is used for a keystroke. It works fine for function keys but not
for alphas. Moreover it doesn't happen on every machine I test it on.

 Some example results are:

20180724 20:24:37 R AltA INKEY:           97
20180724 20:24:41 L AltA INKEY:           286
20180724 20:24:49 R AltA EVENT:           97
20180724 20:24:53 L AltA EVENT:           327745
20180724 20:24:58 R AltN INKEY:           110
20180724 20:25:02 L AltN INKEY:           305
20180724 20:25:08 R AltN EVENT:           110
20180724 20:25:11 L AltN EVENT:           327758
20180724 20:25:15 R AltZ INKEY:           122
20180724 20:25:19 L AltZ INKEY:           300
20180724 20:25:23 R AltZ EVENT:           122
20180724 20:25:25 L AltZ EVENT:           327770
20180724 20:25:31 R AltF3 INKEY:          -32
20180724 20:25:34 L AltF3 INKEY:          -32
20180724 20:25:38 R AltF3 EVENT:          327794
20180724 20:25:42 L AltF3 EVENT:          327794

Has anyone experienced this?

Thanks,
Tim

i have no right ALT Key ... i have ALT  GR = CRTL-ALT
also Inkey() does not have CRTL-ALT

so look into INKEY.CH and APPEVENT.CH to see difference

Thansk for the input.
I have a centralized function that handles keystrokes in a converted
clipper app.
It converts xbase keypress events to clipper key codes to retain
compatiblity with the original functionality.
I think I need to add these additional events (getting two different
ones for right and left alt keys with alpha characters) to the
event->inkey mappings.
But this is wierd behavior and does not occur on all machines so
wondering if it is a hardware issue or something.
All of  our keyboards have two alt keys positioned to the right and
left of the spacebar.

After further analysis the right alt key + alpha is returning the
ascii code for the alpha character from AppEvent(). The left alt key +
alpha returns the proper xbeK_xxx event code for the alt key
combination. This is only an issue with alpha alt key combinations and
not alt function key combos. 

 I''ve opened a ticket with Alaska support and will post any results
here.
