yes they appear to be leaking at the meeting rail, (where the top and bottom window meet and where they lock). No where else does this condensation appear.
The condensation on the exterior of the window is the result of the thermal bridging of temperature from inside to outside. The best performance in the window is at the center of glass (COG). This is why less reputable sales people quote COG numbers for their U-factors and R-Values.
At the meeting rail and glass edge (spacer), more of the interior temperature will be transmitted to the exterior surfaces of the window. If you have high relative humidity outside and a slightly cooler meeting rail, you will see some condensation form on the meeting rail and edge of glass.
If we have high enough relative humidity outside (hot and muggy), it only takes a few degrees difference to form condensation.
If you phrased your post as a question, rather than an assertion and slam against the manufacturer, you will probably get more feedback.
There are several dealers for Soft-Lite, myself included, that would not carry that product line if we identified it to have defect.
Best of luck and please keep us updated.
