I attempted to find the Laplace transform using the usual commands

restart;
with(inttrans);
assume(0 < a);
laplace(FresnelS(t), t, p);

to obtain the result :

I'm unsure as to why this is occuring. It seems that Maple may have  unsteady memory management. Any help appreciated.

Thanks dharr 8927 - I'm thinking that Maple may have been trying without the "assuming positive", and tried it as an option when I failed to include the assumption??

Correct - shutting down and restarting the session (a pain when one has a lot of open files!) will refresh the system. I don't know about the architecture of Maple internally - but it seems as there is a memory "leak" assocaited with the Greek alphabet (and possibly other symbols)

@Thomas Richard  I just want to view the content of .ws files within my working directory. Mapleplayer doesn't provide the content of a .ws file within the viewing pane, you still have to load all the files. I just want a simple VIEWER capability.
