335 Issue - Crashes Entering RA/DEC

When entering the RA & Dec for a target, it seems as I enter text that makes an invalid position, SGP immediately crashes. For example, the starting value for the RA hours is 00, if I enter 23 in front of 00 (so to get 2300) with the intent of hitting the del key twice to delete the 00 (making 23), SGP crashes before I can type del. Same for Dec. Deleting the 00 first and entering 23 works.
