ECL IDE overwrites clipboard

I am using

• ECL IDE 6.4.2-rc1
• Client Tools 5.6.4-1
• HPCC Server 5.6.4-1

When I run some long workunits I usually keep programming in ECL IDE (or other apps). I have found that randomly (but pretty often) ECL IDE replaces the content of clipboard with this:

cd C:\Users\foleyo\AppData\Local\Temp\
C:\Program Files (x86)\HPCCSystems\5.6.4\clienttools\bin\eclcc.exe -showpaths
~

It happens only when I am running a workunit and it happens several times during its execution. Other members of my team have the same problem. It is disruptive because it affects my copy&paste.

As a general good practice, Windows Applications should avoid affecting clipboard...
