Hi,
This issue is related to some of the others....I was using the 1.11MSBeta and was fine...then when I initially tried to update to 1.20 when it first came out...my access controls were snafu'd...but when I back dated to the MS1.11Beta again, they were fine... I posted a thread about thiscouple months back, altho the time issue was minor because the Access controls were messed.
I did see the Invalid Time error when I went to modify a control that wrapped around midnite... I had to break it up as suggested...but I went with 10:00 pm to 11:59 pm for schedule1 then 12:01 am to 10:30 am for schedule2. I had to create 2 access controls; one for each schedule referenced.
when I updated last week to 1.2105 Beta, they seemed to be fine....
