ADDITIONAL OS VERSION INFORMATION :
Windoes XP SP2

A DESCRIPTION OF THE PROBLEM :
If the value starts with "0." and the cursor is before the decimal point, the
cursor is incorrectly moved to the right of the decimal point after the first
entered cypher.
If the value does NOT start with "0.", for example "1." everything is ok.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run.
Move the caret to the right of the initial zero and enter "123".

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
123.00

REPRODUCIBILITY :
This bug can be reproduced always.
