We also experience the problems reported in bugs item #3043838.
The first opened pdf file in the Shim session is displayed properly. The second or sometimes the third or fourth
result in a blank page. Only in one occasion even the first file opens in a blank line.
If we shut the first file (i.e. if we have no opened files in the same faulty Skim session) and open a new file,
this sometimes is shown properly, but some other times appears in a blank page. Only quitting skim an
starting another Skim session, the first opened file is displayed properly, but the second etc. do not.
We reinstalled the old Sim v1.3.19(70) and it seemed to work fine for a while. But then the problems reappeared.
Probably the problem is not with 10.5.8 Leopard: curiously, we have a twin PPC also running 10.5.8. There, Skim
v 1.3.10 (59) gives no troubles.
