FMS Troubles

Just a couple of quick things I've come across with the FMC. I did not see these posted elsewhere, so if this is a repeat posting I appologize.1 - Clicking Delete and selecting the LSK by the RWY entry on the LEGS page causes FS to hang.2 - I don't seem to be able to enter a missed approach point on the legs page. I was trying to enter an intersection after the RWY entry on the LEGS page. Entered the valid intersection in the scratchpad and clicked the empty LSK beneath the RWY entry. Nothing happened.Despite the problems that have turned up I enjoy flying this aircraft and I look forward to the patch.Thanks!
