Keyboard constraints won't work. . .

[nalik]

In Illustrator

A few different things won’t work. The main problem is constraining a box or circle by using the modifier keys. Also when I use the zoom out tool it will zoom in and out in an erratic manner. When you press space bar it is supposed to switch your cursor to the hand or grab tool that wont respond at all. These are only a few of the problems.

Thanks for the help.

Which version of Illustrator are you using?
Has this always been an issue or has just started?

is there an answer to this question? It happened to me, too!
I'm using Illustrator CS.

Nalik:

This sounds like an aiprefs issue.

Aiprefs is a file that stores all of your preferences (the ones you set through Edit>Preferences and many more things, like palette placement, envelope settings, etcetera) and each time you close Illustrator it updates any changes that you may have made during that session. The aiprefs file frequently corrupts, and that causes issues like the ones you're describing. The solution is to delete the aiprefs file and let Illustrator build a new one (it will do so upon the next exit). After deleting aiprefs, Illustrator will be restored to the original prefs, so you'll need to customize everything all over again.

Here's what you need to do:

1. CLOSE Illustrator (ESSENTIAL!!!);
2. Go to the Windows search dialog, enable search for hidden and system files, then do a search for "aiprefs", without the quote marks, no extension;
3. When you find it, delete it;
4. Fire up Illustrator;
5. Customize the layout and preferences to your liking;
6. Exit Illustrator, then go to the aiprefs location and copy the file, save it as a backup so in the future you can just drop it into place...
