I did some quick Googling and the solutions seems to be in tablet PC input settings, here is a link you can check out for a step-by-step with pictures.

To resolve the issue you will need to edit the registry.

1. Press Windows Key + R to open the run prompt.
2. Type regedit
3. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows
4. If you see something called MenuDropAlignment double click it, if not follow the steps below 4a. Right click in the white area in the right hand pane 4b. Click New, then String Value 4c. Name it MenuDropAlignment 4d. Double click it now to open it
5. In the value data field type "1" without quotes for it to open to the left, for the right type "0"
6. Close regedit and log off and back on for the changes to apply. Might have to restart computer, not sure.
