Sorry to hear you're facing these troubles and thanks for provided minidump file. We've analysed it, but unfortunately, in this case the minidump doesn't clear the problem - it seems to be linked to the pen tablet driver. We've been doing some tests on 3ds max 2012, RailClone Pro 3.0.7 & the 1.7 DailyBuild Jul 10 2017, but we can't reproduce any similar troubles.
Let me mention, that we always recommend to use the latest version released (please feel free to check our Release Notes
website, where you can find all new features, improvements and bugs fixed since you've acquired it)
If you can send us
any "affected" scene, it would be great. Thanks in advance for any further comments on this issue you can share about it with us / our user community.
