slight possible leak issue has sprung up (no pun intended at all

)
about 2 thirds up the right hand side of the front panel i have a drip/trickle sometimes. been going on for couple of days. wasnt there yesterday but returned a bit tonight when i finished work, could be due to the top pvc covering not fitting tight and the condensation running between i small gap where the acrylic meets the front frame. there is obviously loads of silicone there but there are small pockets which look like, from inside, are harbouring a drop or two of moisture. i'm hoping that's all it is. oh bollo?ks, here we go again
