In the version name for Spark 1.1 (Help > About) it shows up as 188.8.131.52.
If you use Spark Manager, and then check for updates with Spark, it will tell you a new version is available, version 1.1.0.
I guess a work around would be renaming the files 1_0_5_1 (haven’‘t tried, but guessing at it), but that shouldn’'t have to be so.
Love the way Spark is coming along. Great job.
