When navigating between parallel Hebrew lexica (with left and right arrow keys) the parallel resources icon disappears in some resources. For example if I open up this entry in BDB, and then click right through parallel resources the icon disappears in HALOT, CHALOT, Gesenius and Strong's concise dictionary, but not others. In each case scrolling up or down in that resource makes the parallel resources menu reappear.
It's not a pressing issue since the arrow keys to move to the next resource still work, but could be confusing or an issue for someone who doesn't navigate with the keyboard.
