Hi

I am getting an error message displayed on some slides when I press the NEXT button. The message says Next Slide: Invalid argument.

This has only started happening since I upgraded to 2.4

The strange thing is that other Next buttons in most of the rest of the module are working, it seems to be just one or two that are doing this.

Anyone come across this ?
 

Hi, Bob,

Is there any possibility that these "defective" slides are using the same master-slide? In general - is there any common slide properties.
Also please try to run object's update (menu Module - Update objects) - there could be some changes in 2.4 object/runtime interaction, that need updating.  

Hi

This is happening to me a lot in a particular module. I am creating a number of slides and checking them. I then add graphics and they refuse to move forward or backwards. If I delete the graphics then they still refuse to move and I have to recreate the slide from scratch.

I have tried to update the objects but that hasn't worked.

Any suggestions ???  

OK I may have sussed this. When I use the text editor I use a font called Microsoft Sans Serif, its about the best low res screen font I have available.

Often however I notice that some of the spaces and some of the font displays @Arial Unicode MS as the font being used.

If I copy the block of text to Word, format it in the correct font then it all works OK.

Don't know what this font is as it does not appear in any other of my programs  

Hi Slav,

Course Lab is an extremly useful tool when it comes to building e-learning courses.

Well I was developing a course and when I run the module, it gives an error which sates "Next Slide:Invalid Argument" and when I try to hit the back button, I get "Previous Slide:Invalid Argument". I have only 1 master slide and as you suggested earlier I had 'updated the objects', but it doesn't seem to solve the error. Any ideas as to why this might be occuring? Any help will be greatly appreciated!!!

Thank you in advance,
Cheers,
