That seems weird. I did a quick test setting the tempo at 110 for the 
entire song and placing the playhead at exactly the end of measure 109 
(or the start of measure 110), and the transport indicates 3:57. See a 
screenshot here:

Hint: in Rosegarden you can move the playhead exactly 1 measure at a 
time by using PAGE-UP and PAGE-DOWN keys
Also, the transport windows is clickable and you can enter an exact 
location in any of the supported formats (

Maybe I would check a couple of things:

- 4:02 would be around the end of measure 111 at 110 BPM, so are you 
sure you are at the end of 109?
- 4:02 would be the end of measure 109 at 108 BPM. Are you sure the 
tempo is 110 BPM for the whole song? Sometimes when dragging the tempo 
line in the tempo ruler I have set tempos of which were from .50 to even 
2-3 BPM off. In fact when I want to set a fixed tempo I prefer to right 
click and actually input the numerical values...

Just my two cents, but then if the above two are correct let's hear what 
others have to say :-)
