Graham, 

My experience is with cerevisiae, but perhaps it will help. First, we mix agarose with synthetic medium (aka SC).  It's less autofluorescent than our yeast extract-based medium (YPD). Second, we use a thinner agarose layer. Our agarose pad is < 100 um thick  but the cells are fine for hours. 

In our hands, a simple glass-slide mount does not support normal cell physiology for very long (~15 min).

For details, feel free to e-mail me off list, or see

Good luck,

This works very well for confocal microscopy, but recently upon trying
widefield microscopy we have noticed a significant background
fluorescence, presumably from the agar.
