How to dry the DDRT-PCR gel?

Dear Netters:

According to the current protocols in Molecular Biology, the diffferential 
display of 6% denaturing PAGE/Urea gel is dried at room temperature for 
about 1 hour.  Is that any reason the gel can not be dried with heat?  
I have tried to dry it at RT for 1 hr and overnight.  For 1 hr, the gel wasn'
t dried at all.  For O/N drying, the gel was broken into pieces.   
These 2 gels were dried without vacuum.  One publication said the gel was 
dried on the plate or transfered to a filter before exposed to X-ray film.  
Do these people dry the gel without vacuum?

Any suggestion would be very much appreciated.
