SiDiary Beta 6 En New Bug? Update 25-Oct-08
SiDiary Beta 6 En Profile is set to Virtual Day to help with control of Type I ICT and post-midnight BG tests. I have encountered a problem when entering a BG value after Real Day midnight. When I click Save on the Log Book page, the entry completely disappears -- time, BG value, and Insulin dosage.

The pop-up box with two radio buttons appeared: [F11] for the prior "Real" day (23 Oct), [F12] for the current "Real" day (24 Oct). I selected the radio button by F11. When I pressed the [F11] key nothing happened. I cleared the entries and repeated the process but the data still disappeared and neither F11 nor F12 had any effect. The data entries disappeared.
This happens most times whenever the reading time is after midnight. When I discovered that the data entry "moves" to the real time previous day as intended when using Virtual Day, I thought the problem was resolved. However, last night the entry disappeared and did not appear on the previous day, nor on any graphics such as the line graph or detail statistics.

I completely closed SiDiary Beta 6 En, including the System Tray. I then relaunched Beta 6, opened Log Book, and tried the entry again. The data entries again disappeared.
This morning, after restarting the Vista SP1 PC, I launched Beta 6. I tried changing the late night event time from the actual 0105 to 0110. In this instance the data remained, appearing on the current day but at the correct early AM time.

Late night post-midnight entries are often test times for me, so this is an important issue.
Update: 
The Graphics > Line Graph > with
Show Bolus and Basal checked revealed that the apparently missing data appeared on a previous day, 22 Oct. There were several duplicated entries for BG Bolus and Basal with 0100 or 0105 time stamps. The clue was duplicated Bolus bars on the BG graphic. I clicked the bar for the duplicated Bolus and Beta 6 opened the Log Book to the date of the Bolus. I then had to manually delete the duplicates, which apparently happened when I click the [F11] key but the entry did not seem to appear on 23 Oct.
After I deleted the duplicated entries, the data automatically moved to the correct 23 Oct date.
Hope this helps with the debugging process.
