Solution for "sticking" windows

[Tinsu]

I mentioned to my dealer that the large window over the sink was sticking when I opened it. He said it was common for new ones to stick, especially in a hot summer like this. He suggested spraying the track with silicone spray (not WD40). Just thought I would mention this for those who are experiencing the same problem.

using a "pounce pouch" with baby powder also works well and doesn't swell the seals....
