Hi Patrick.
Thanks for the bug report. I took a quick look at the potential cause.

Here is a very simple workaround (i.e. I haven't investigated the other
side-effects):

diff -r1.28 devPS.c
1033c1033
<     if (pd->lty != newlty || pd->lwd != newlwd) {
---
>     if (pd->lty != newlty || pd->lwd != newlwd || 1) {  

In other words, change the if() condition in the routine SetLineStyle()
in the file src/main/devPS.c to be true, regardless of whether the
values are the same or not. This appears to give the desired result.

Hopefully we will determine the appropriate reset configuration
as page changes occur. Anyone.... ?

D.
