When tabbing through the workplans actual dates making modifications or adding new dates, IE will randomly lock up for minutes at a time, even up to the 10 minute timeout we have configured for PPM. Sometimes it recovers and continues on working however the field that you were on at the time no longer autopopulates the date if you enter for example: 1/1 and tab away. the rest seems to function correctly. This only repros with IE 7, not with firefox. Does anyone else experience anything similar?
