LNT – Mails disappear from inbox

Recently I posted that an update for Lotus Notes Traveler is available. Today I saw that this fixpack  causes problems.

When you receive a new mail, this mail is synced to the device. When you open the mail on the device, there is no problem, except that the unread mark is not exchanged with your client and the mail remains unread in the client inbox.

But … when you open an uread mail in the Lotus Notes client, the mail disappears from the inbox on the device.

I reverted back to 8.5.0.1-LNT-LO37251 and the mails stay on the device when read in the Notes client.

Anyone else who can reproduce this behaviour?
