I pondered over this problem for some time now checking for possible conflicts.

The problem is for example - RT Simplix template which has integrated Rokzoom.  When template installed the default is Rokzoom "enabled".  Install, Switch on the mambot "rokzoom".  Ok so far?  Good. Give it some pictures to display - it works. (Well sort of because you have to create your own thumbnails) But as some of you know, each picture must have it's own syntax, to give it title or picture info. 
eg:{rokzoom title=|somepicname|}images/stories/gallery/image.jpg{/rokzoom}and so on.
Laborious!  Might as well enter html!

Switch off mambot or delete.

Install SIG pro.  Enable, point it to same folder of pictures or another and what happens.  Blank thumbnail with red cross and image opens in new window.

Cannot figure why but I have deleted all references to rokzoom, ie; folder and comment out line in template.  Still no joy.

As SIGpro has own js engines I do not know why there should be conflict.  It seems that rokzoom leaves a trace somewhere and blocks call to the SIGpro scripts.

Anyone got any ideas?

Hi my friend!

Do you have check all the others engines of SIG Pro, as Lytebox or Greybox
that use other javascript library, as JQuery?

Could be a mootools conflict cause of multicall of this library.

A direct link to the problem could be very helpful to understand what happens!

Thank you!

Hello.
I think I solved the problem with fatal error call to the php script on line 138. Which causes thumbnails not to be generated.  The php_gd extension was not installed or enabled on my local server, WAMP 5.

Got thumbnails now.

I posted this to let anyone with similar problem - check server!

Now to search for forum for why images open in new window!!

PS. Rokzoom is still installed but switched off.
PPS. Late RT-themes have now been modified to run from mootools.v.1.11
