Open File Dialog - Multiple file selection limited to 7 files?

[OnishiZX]

In a database I use an Open File Dialog to open multiple files using an Array
and then I use the Array to populate a list and process it.

This works great, until I select over 7 files, at which point the array
remains empty without the error handler triggering.

Is there a logical reason and/or solution for this?

Further research indicates that when the number exceeds 7 the following line
starts giving a False instead of a True:

aht_apiGetOpenFileName(OFN)
