I am having a problem with the tape leaving brownish dry spots on harder tissues and even some smaller skin tags. We are using plenty of xylene on each slide. Has anyone seen this Problem using the tape?  I am wondering if our xylene is the problem.  The xylene we are using is good quality, but it is called XYLENES with an "S" on the end.  The coverslipper is brand new and functions great.  I just can't figure out the dry spots in the tissue. Plase Help !
