One possibity is plotting both curves like:

plot([Re,Im](i1(omega)), omega=-15..15);

Another possibility is plotting as a curve in 3D, e.g.:

plots:-spacecurve([(Re,Im)(i1(omega)),omega], 
omega=-15..15,axes=boxed,labels=[Real,Imaginary,omega], 
numpoints=100);

See ?backslash, it stands as continuation character. So, in 1D 10\000 stands for 10000. But the 2D parser seems to interpret the backslash as set operator only.

That help page is not clear about this issue. So, it is ambiguous whether it is an   issue of implementation or documentation.

Better use <pre> tags for input. And check with preview before posting.

Yes, that error message arises in 2D input, because of the bar in 10\000. No such problem in 1D input.

I know, but it is a point. Without the exact code, trying to reproduce the problem is much more difficult...

Have you tried in a fresh session or after restart ?

I think that you could erase the bitmap labels from the png, and latter add them with the editing tool.

These are most interesting news. For sure, I will try these methods when I get a 64 bit PC, probably next year. I hope that they will work also under Windows 7.

In regards to the DOS box, you could create a pif file to call the batch file.

I any case, aren't Maple leaves (as now) a more suitable symbol?
