Hello!
When my application opens a URL in Firefox with more than 257 characters, the URL is truncated and the message below.
"Err: psdrv: PSDRV_PPDGetNextTuple Line too long."
I noted that this limitation may be due to the following code. See line 00363.
Code:
00354 /*********************************************************************

Is there any way around this limitation?
Thank you.
