Hi, I am using 2.10.4 and monobjc 2.0.505. My requirement was to show NSsecuretextfield and NStextfield at the same place based on a flag set by the user. So basically show the password and in some cases mask the password. I implemented this by setting IsHidden = true or false. This code works on 10.5, 10.6 and on some Lion machines. But this does not work on some other lion machines. Is there a way this can be solved ?
