bindkey definitions issues

Got a little problem here. I have a massive set of custom bindkeys defined - these have worked fine for years (with a little process dependant tweaking)...

Recently started a new process - and moved to version Cadence ICADV12.2-64b.400.1 

Now my shift and also control F keys no longer load the associated procedures I have defined in my key.il file.

These issues are specific to the function keys

the regular key (no shift or ctrl combo) works fine

Shift+ the_function key (ex. shift+F1)  does not run the assigned function... instead duplicates the actions of the regular function key.

Ctrl + the function key combos does not work at all... this is true for F1 thu F12

for example:

In my key file I have the following code...

alias bk hiSetBindKey

LAY = "Layout"

SCH = "Schematics"

bk(LAY "<Key>F3"    "leHiMarkNet()")

bk(LAY "Shift<Key>F3"    "leHiUnmarkNetAll()")

bk(LAY "Ctrl<Key>F3"    "listInstancesInViewingArea()")

F3 works fine and performs  leHiMarkNet command

shift F3 does not unmark the net... instead it performs the leHiMarkNet command

ctrl + F3 does not do anything...Nada. 

so...question...is this an issue with teh new cadence version?

Note: To eliminate the possibility that my key file is getting stomped on by the group loads... I have tried to direct load the key assignment via the CIW command line...it looks like it loads fine (no error messages and returns "t"...  but then it still performs incorrectly as described above. 

Suggestions????? any help would be greatly appreciated... since a vast majority of our team uses my custom setup.

Thanks,

Terry
