Version 2.6.3 won't save when there are open Reports

[Roger]

Hi Derek,

I have always agreed with you about residual and have done as you 
suggested so that this was all that was left (actually I think there 
must be some configuration files somewhere???)

Anyway I think I found the residual that was causing the open report 
problem.

Once I deleted the ~/.cache/guile folder everything seems to work!

Thank you both Derek & Geert for you perseverance in helping to solve 
this frustrating problem.

Roger
