'Edit bitmap' command in Draw X5 lost after SP3

Re: CorelDraw X5 v 15.2.0.686 [SP3] + Windows 7 x64

 

After applying SP3 Draw X5's 'Edit bitmap' command is always greyed out, regardless of the bitmap selected — even when the originating file is a CPT.

 

At first I thought of a corrupted Workspace, so I reset Draw with F8 at execution. No dice. This makes me think there may be an odd Registry setting or ini file entry that Draw needs to 'find' Photo-Paint X5. Photo-Paint appears to have emerged from the update unscathed.

Very grateful for suggestions!
