Hi, Mike, Ehsan, and David, thank you!
In the end, I added the Logging functionality to mozglue, exported it, and imported it wherever necessary. Now it works as expected, and there are no noticeable hangings even when working with large applications (e.g. facebook). Just in case, if a beginner like me, runs into a similar problem, this link was also useful: http://msdn.microsoft.com/en-us/library/ms235636.aspx Thank you, Josip On Wednesday, October 29, 2014 12:19:03 AM UTC+1, Mike Hommey wrote: > On Wed, Oct 29, 2014 at 08:08:23AM +0900, Mike Hommey wrote: > > On Tue, Oct 28, 2014 at 11:56:49AM -0400, Ehsan Akhgari wrote: > > > On 2014-10-28 4:16 AM, Josip Maras wrote: > > > >Hi Ehsan, > > > > > > > >Yes, in my opinion that is the problem.
