FW: Troubles creating job schedule

Hello,

This is my environment:

Client side: Windows 7 Pro, sp1
Server: PostgreSQL 9.5.7 on x86_64-pc-linux-gnu, compiled by gcc (GCC)
4.8.5 20150623 (Red Hat 4.8.5-11), 64-bit
PgAdmin 4 Version1.6
Python Version2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:42:59) [MSC
v.1500 32 bit (Intel)]
Flask Version0.11.1
Application ModeDesktop
pgAgent: v3.4

I'm having troubles creating a job schedule, within the pgAdmin UI. I can
create a job and one or more steps for the job. I can verify this by
checking data in the tables within the pgagent schema. Looks good. But
when I attempt to create a schedule, pgAdmin hangs, and I'm forced to kill
it.

In the "Create - Schedule" dialog, as soon as I click on the "Start" or
"End" date fields, it freezes. It doesn't matter whether I have already
filled in the other fields or not.

Is this known or a new issue? I didn't see any previous posts with the
keyword "schedule".

Regards,
Scott.
