4.6c / SAPGUI 640 buffer issues

[Sample, Rick]

I am having some REAL ANNOYING issues with this 4.6c / SAPGUI 640 combo!
We are at svr pack 50. I know this is a tad behind, but my other
developer who did 
not install the new SAPGUI to 640 is not experiencing my issues.
 
Issue 1:
I open PFTC_CHG make any changes to the template then,
switch to Display via icon and I get short dumped. Every time.
I see an oss note for this issue. 
 
Issue 2: (Most annoying!)
I make changes in WF template, SWO1, or FM via SE37 and I DO NOT 
get the updated code changes when I run a new instance of the WF. 
I have tried any and all ways to refresh buffers but the only thing I
can do 
to ensure I have the new version of code changes is Shut Down SAP GUI
and 
re-login. That is VERY ANNOYING!
 
I tried to uninstall the new SAPGUI and re-install the old vers. No go.
Reinstalled 640. no go.
 
Anyone experienced this and have a solution - please let me know! 
I entered a customer message for this but dead lines are approaching 
and this issue is killing my productivity!
