Strange measurement input fields behaviour

Question

Hello,
I have a Czech version of Illustrator CC on Windows 7 Pro.
Some measurement input fields are not working as expected, for example:
When creating a new document:
Decimal marks in document dimensions have disappeared (instead 210.00 mm it shows 210 00 mm). It also disappears after I add it. Another strange thing is when I click in the input box, do nothing and click out the value changes to 5779 55 mm
(Something similar is happening in my InDesign: I can't change an object's dimension expressed with a number with a decimal mark to another number with a decimal mark - only to an integer. I'm not working in Web mode.)
Is this behaviour controlled by some settings I can't find or is this a bug?
Every note leading to a solution much appreciated!

maara,
The decimal point is basically governed by your Regional/Language settings, in the Control Panel I believe.
There may be some issues between . and , for decimal point (and reversely for thousands).
But, especially if the behaviour has not always been there, you may try the list below.
In any case you may try a chat or a support call, here or here,

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.
If possible/applicable, you should save curent artwork first, of course.
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.
