We have a RadMaskedCurrencyInput control defined as:
<telerik:RadMaskedCurrencyInput Margin="20" Culture="se-SE" Placeholder=" "/>.
If we focus the control and press the LeftArrowKey, the cursor is placed on the last (far right) position in the control which is incorrect.
=====
Reason for deletion: You can consider Placeholder = " " as a risky setting that might lead to unpredicted parsing results. We highly encourage you to avoid using it. Instead you can use no-mask. In this scenario you can use:

 <telerik:RadMaskedCurrencyInput Margin="20" Culture="se-SE" Mask="" FormatString="c2"/>
