Can you confirm that the version of the controls that you are using supports IE10? The first version would be Q3 2012 and I would advise that you try it with the latest (Q1 2013 SP2 presently, 2013.1.417 in numbers).
If this does not help I would advise that you check how you add the control to the form, if it is dynamically created can you confirm it gets the same ID every time?
I am not aware of other problems in this regard and if you still cannot resolve the case I advise that you post the code that leads to this problem so we can reproduce this behavior in order to debug it and see what is causing it.
