I have now tested some more. Holding down ctrl helps allot when dragging the handle. When I am entering a time code in Button properties – Media – Thumbnail – Start time. 100 will give me the time 00:01:40:00(100 sec). 90 will give me 00:00:03:15 (90 frames). 090 will give me 00:01:33:15 (?) the only logic might be if 00:01:30:00(90sec) + 00:00:03:15 (90 frames). 03000 will give me 02:50:00:00 (?) 3000 will give me 00:50:00:00 (3000sec)
Is it only me or does some one else have this problem?
