Condensation inside perspex double skinned window

Did a repair on the high top double skinned perspex window of my westy atlantic using method shown in one of the forums. Basically I split both skins in two and replaced the cracked inside skin using a cut sheet of perspex bought from B&Q. I then sealed with silacone sealant & clamped both skins together, left to dry overnight and refitted the next day. Before I sealed the two skins together I made sure that the two halves that went together were clean & dry. I'm now having a problem with condensation between the two skins

Would drilling a small hole insde help clear it

Sounds like you`ve got damp air trapped inside it, some original factory windows have small holes drilled in them, with plastic bungs to seal them. One of mine was steaming up internally, I removed the bungs and let it dry out for a week when it was sunny, I then used a hair-dryer to warm the inside face of the window (not to much) and then quickly sealed the bungs back in with a smear of silicone. The idea being that the air inside the unit would be warm and dry, then when sealed up it cools down and contracts forming a partial vacuum. Been fine ever since
I have seen something about putting a few grains of rice into the unit through the small holes, this stuff will sit in THE bottom of the unit and absorb any small ammounts of moisture.
