Possible Resources Leak

Well-known member
I cannot say for certain, but I think that there may be a resources leak of some sort with the program. Ever since installing it, I've found that running it will periodically cause a situation where I cannot open new PDFs and even trying to load the Task Manager provokes error boxes stating that the system is out of resources. And, sadly, it doesn't entirely go away when I close Hero Lab.
 
first off i wold try to reinstall it. then if that doesn't work you might want to run a registry cleaner. Norton Utilities is the one i recommend. You can get a free 30 day trial of it on their website.
 
Does the problem occur with Hero Lab alone? Or is it an issue that occurs when generating PDF files? This is an important distinction that has significant impact on how we go about trying to verify a leak is occurring.
 
It shows up in one of two forms. I will either try to open a PDF (an extant one, not one I'm generating from HeroLab" and get a message saying that there are "insufficient resources", or I'll step back to HeroLab and find that none of the tabs are displaying (in this scenario, I've always found that the PDFs also report insufficient resources. Closing an already-open PDF allows me to open another PDF, but once this happens, closing HeroLab does not seem to free anything up, as I get the same error on PDFs and tabs are still missing if I reinvoke HeroLab. Restarting the computer is the only recourse.

I am still not 100% sure this is HeroLab, but it started happening after installing HeroLab.

And also, I have not run into this again since installing CCleaner and reinstalling HeroLab, but I'll keep my eyes out.
 
Keep us posted. We're pretty good about memory and resource management within our code. When it comes to system resources, all of our access to Windows mechanisms is encapsulated in a small number of very fundamental mechanisms that we use everywhere. Consequently, if there is a resource leak, it should be pretty obvious to everyone. And that underlying code hasn't been touched in many years.

The key exception is with the PDF mechanism, since we needed to write appropriately for public disclosure of the source code. So I'll be stunned if there is a leak within HL itself, but I won't be so surprised if there is an unintentional leak in the PDF logic.

Keep us posted on whether you encounter this problem again. And please provide as much info as possible if you do. Figuring out where the leak is will require that we actually trigger the leak on our end. :-)
 
I'm starting to think that it's something else, because the effects are too far-ranging and I think I had it happen one time when I had not invoked Hero Lab at all. I will keep you posted if I learn anything more.
