Cameyo

Hi,

We've had some issues when using the Cameyo tool to package our software. Most of the time the tool works fine, and runs precisely as it does when installed normally, but in certain circumstances we are getting two different issues.

1. Open File Dialog bug

One of the forms in our software uses the generic .NET OpenFileDialog API in order to request a path to a file in windows. When doing this, we occasionally get the navigation options missing. See attached image OpenFileDialog.png for a screen capture of this.

2. Crashing

When running a particular set of steps in our software with a very large file and large RAM requirements, we are getting frequent crashes with "<Software Name> has stopped working". See image Crash.png for one of these.

The details of these crashes can vary. They are always instigated by either the module "AppVirtDll64_Deswik.Suite.Portable.dll", or by "KERNELBASE.dll". The error codes returned point to an access violation error (problem with memory usage in unmanaged code). Our software is all written in .NET, which is managed code.

We ran a process monitor tool to attempt to discover more details about the particular error. We aren't certain that the following stack trace is related, but we discovered using the process monitor that there were several file IO calls just prior to a particular crash which had some awkward results. See process monitor.png for these.

The stack traces for the various lines are:

Any assistance with either of these two problems would be greatly appreciated.
