Question

The scaling selection using SHIFT doesn't seem to be working for me all of a sudden.......how can I resolve ?
Specifically, when I select and object I used to be able to hold SHIFT while re-sizing the object and keeping it in scale.
All of a sudden, I don't have that option as my SHIFT key doesn't seem to activate within AI

B,
You may have something disturbing Illy so she gets confused, see Item 7 in 5) below for usual suspects, or you may have what appears to be a preference corruption, see 1) - 4) and 6) below.
The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to 3 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.
