I've just installed the Hotfixes (1 & 2) for SP5 and from the Domino Console the "Tell Bes About" returns 4.0.5.15 but in the Server List on BlackBerry Manger the BES Version is shown as 4.0.5.5 still.

Is this right?

check in the release note for a paragraph which you can verify the bundle number after installation under Add/Remove Programs, click on support information.

The number increments in the Tell Bes About (4.0.5.13 for HF1 and 4.0.5.15 for HF2) so I know its installed.

I see this as well. Don't think it is a problem, just a display bug.

No worries
