In a modal dialog, when tabbing to next NSTextField, or programmatically selecting a NSTextField, the NSTextfField that is loosing focus (aka resigning FirstResponder) appears empty in Tahoe 26 ( aka not displaying its content) . The same thing works oK in all systems before Tahoe. Found no workaround this issue which looks to be a Tahoe problem.
i have a small app that demonstrate the issue.. but cannot be posted here due to zip format not accepted...
i appreciate any help or apple engineer attention to that issue also posted with Evaluation Assistant under #FB21102969 ThX
