IMAQ limitations

Hello,
I've got just one single question:
Does anybody know if there is a limitation in the number of lines or the ratio X-lines/Y-lines for images when using IMAQ ?
 
We've got some problems with IMAQwrite and IMAQWindraw (Labview v5.0 and IMAQ v.2.5.1.).
Everything works out fine until the Y-line number exceeds something around 38'000 (X-Lines 214). With 32000 lines in Y our program runs perfectly well.
It does not seem to be a memory problem; we tested this using a RAM cleaner, which displays RAM usage during all the tasks and we are not even near the limit.
Anyway, we already used the program to handle larger images (in terms of Mbytes) but wit fewer lines in Y.
 
And is this problem corrected by newer IMAQ versions ?
 
Thanks to all

In the latest versions there is no such problem.

Have you verified  the index type of your input. Looks like it is an I16 number.
